No, that's a too generic exception, and also IMO not used correctly here. If we are to treat this specific case in a unique way we need to introduce a new exception type just for this. I would suggest `BadCommitMessageException` (extends `RuntimeException`). This becomes a contract between `PullRequestCheckIssueVisitor` and `CheckRun`, which can then catch just this exception and make it an integration blocker.
